"Activate when: user asks 'does this business have a moat', 'what stops competitors from copying us', 'how defensible is this company', 'is this advantage durable', evaluating a company for investment or acquisition, designing startup strategy for long-term defensibility, reviewing an investor pitch's competitive-advantage claims.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Economic Moat ## Overview An **economic moat** is the durable, structural competitive advantage that protects a business's returns on capital from being competed away. Popularized by Warren Buffett (1986 Berkshire letter); codified into five sources: intangible assets, switching costs, network effects, cost advantages, efficient scale.

How to install
mdr add deciqai/knowledge-skills/economic-moat@sha256:65383f6e6db6689fThe line at the top of this page pins the label git:20261025.cb4e537, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
